33A. Wood-Aged Beer

This style is intended for beer aged in wood without added alcohol character from previous use of the barrel. Bourbon-barrel or other beers with an added alcohol character should be entered as 33B Specialty Wood-Aged Beer.

Overall Impression

A pleasant enhancement of the base beer style with the characteristics from aging in contact with wood. The best examples will be smooth, flavorful, well-balanced, and well-aged.


Varies with base style. Often darker than the unadulterated base beer style, particularly if toasted or charred barrels are used.


Varies with base style. A low to moderate woody aroma is usually present; some varietals may have a stronger, or distinctive character. Fresh wood can occasionally impart raw, fresh-cut wood smell, although this character should never be too strong. If the wood is toasted or charred, there may be low to moderate vanilla, caramel, toffee, toast, or cocoa character present.


Varies with base style. Wood usually contributes a woody flavor, and possibly a distinctive varietal character. New wood may add a raw, fresh-cut wood impression. Toasted or charred wood can add vanilla, caramel, butterscotch, toasted bread, toasted nuts, coffee, chocolate, or cocoa, depending on the wood varietal and level of toast or char. Wood-derived flavors should be balanced, supportive, and noticeable, while not overpowering the base beer style.


Varies with base style. Tannins from the wood may increase the perception of body, as well as enhancing the dryness of the finish; some astringency from wood tannins is allowable. Tart or acidic characteristics should be low to none, and never distracting.


Much of the character depends on the type of wood used, and how well it complements and enhances the base style. Age character is allowable, but excessive oxidation or sourness is a fault. Noticeable alcohol is not a fault in stronger base styles.
This category should not be used for base styles where wood-aging is a fundamental requirement for the style (e.g., Flanders Red, Lambic). Beers made using either limited wood aging or products that only provide a subtle background character may be entered in the base beer style categories as long as the wood character isn’t prominently featured.


A traditional production method that is rarely used by major breweries, and usually only with specialty products. More popular with modern craft breweries looking for new, distinctive products. Oak cask and barrels are traditional, although other woods are becoming more popular.

Characteristic Ingredients

Varies with base style. Aged in wooden casks or barrels, or using wood-based additives (e.g., chips, staves, spirals, cubes). Fuller-bodied, higher-gravity base styles often are used since they can best stand up to the additional flavors, although experimentation is encouraged.

Entry Instructions

The entrant must specify the type of wood used and the toast or char level (if used). If an unusual varietal wood is used, the entrant must supply a brief description of the sensory aspects the wood adds to beer. Entrant must specify a description of the beer, identifying either a Base Style or the ingredients, specs, or target character of the beer. A general description of the special nature of the beer can cover all the required items.
